The 2nd generation AM2+ motherboards are coming very soon (790FX/SB750), I would wait a bit for them to arrive (~ 2-3 weeks I guess). The SB750 is able to clock the Phenom even further if you're interested in overclocking.
Well I just got a Asus M3N-HT Deluxe Mempipe in on Saturday. Took the Phenom 9850 off the Gigabyte GA-MA790FX-DS5 which maxed out @ 2800 Mhz overclocking and slapped it on the Asus using the same ram, powersupply, videocard, cpu and heatsink. So far up to 3300 Mhz stable and still pushing it further. Gonna try the 6400+ BE on it next to see how far that can be pushed. Could only get about a 100 Mhz bump OCing with it on the Gigabyte.
